Parliament will be voting on a motion which could reduce the rules on Sunday opening – a little bit. But the government urging MPs to reject it.
A Valais parliamentarian, Philippe Nantermod, says small grocery shops should be allowed to trade on a Sunday.
He adds automated checkouts has reduced the need of staff, so the impact for people will be less.
There are already exemptions. Shops in train stations and tourist areas can open. As can restaurants, bakeries, cafes and small family-owned businesses.
The government says the majority of the people have consistently demonstrated they like quieter Sundays.
